摘要： A display apparatus includes a display panel including address electrodes and sustain electrodes crossing the address electrodes, with pixels being sandwiched between the address electrodes and the sustain electrodes. A sustain-electrode drive circuit selectively generates both sustain pulses and scan pulses and supplies them to the sustain electrodes. An address-electrode drive circuit generates address pulses based on a video signal and supplies the address pulses to the address electrodes. A control-signal generation circuit generates a control signal for controlling the sustain-electrode drive circuit to generate a selected one of the sustain pulses and the scan pulses and supplies the control signal to the sustain-electrode drive circuit. In order to display an image on the display panel, the sustain-electrode drive circuit both specifies addresses of pixels to be turned on and turns on the pixels at the specified addresses.

摘要： In conventional plasma display devices, reset by obtuse waves has been performed since discharge intensity becomes higher and background light emission is increased when reset by rectangular waves is performed. However, further improvement of the contrast to improve the image quality has been demanded. The present invention provides a driving method of a plasma display device using obtuse-wave reset in which sustain time of an achieved potential of the obtuse-wave reset is controlled in accordance with a display ratio of a video signal.
